The embodiment of Fig. 2 Yu Fig. 4 is to build the pedestal with four lower limbs (or equivalent structure).Each shaping Plate 26 have extended about 90 degree of arcs upper end and limit for the lower end of the installation of single footing, this single footing Then it is designed to install to single base leg.There is the pedestal of the such as lower limb of the varying number of three lower limbs or five lower limbs etc Or the pedestal on the bank that even formed by flat board or or other type of structure, it may include the forming board of varying number 26 and footing 32.In the case of the quantity of forming board 26 is different from 4, each forming board is likely to have and prolongs Extend through the upper end of the arc length being different from 90 degree.

According to some embodiments, forming board 26 as shown in Figure 4 can be built into by some less daughter boards.Borrow Embodiment, Fig. 5 is helped to show in three daughter boards 60 that can be used for forming the base structure of the plate 26 shown in Fig. 4 Two.Each daughter board 60 shown in Fig. 5 can be cut by single steel plate or other material and form, and shaping Journey bends along shown folding line 62.Shown daughter board 60 can be soldered to the 3rd central authorities' daughter board (Fig. 5 does not shows Go out) thus form the base structure of plate.Then, can by flange and ribs (not shown in Fig. 5, but above the most Contact forming board 26 is been described by) it is soldered to base structure thus improves forming board 26.

The embodiment of forming board 26 can include the multiple spy providing intensity (especially preventing flexing) when compression pressure Levy.As it has been described above, the overall shape of the general curved of forming board 26 and/or conical overall shape provide to a certain degree The intensity of antagonism flexing.It is disposed at least substantially parallel to the bending that compression direction (that is, being parallel to the column of pedestal) extends Part 42 can further help in and prevent flexing.Such as the solderable reinforcement being connected to forming board 26 surface (usually inner surface) As rib 44 is accomplished, the flange 24 being positioned at upper end and the flange 28 being positioned at lower end and along forming board 26 The flange 48 and 58 at other edge also provide for resisting the intensity of flexing.According to some embodiments, forming board 26 The combination adding the positioned alternate strong rib 44 on plate 26 with bending member 42 can be included, thus both enhance structure And optimize material use.But, other embodiment be also feasible and it is conceivable that, this includes having the most fixed The embodiment of the ribs 44 that position positions at bending member 42 top or next-door neighbour's bending member 42 and complete ribs useless And/or the embodiment of bending member.

Ribs can be built by different way.According to some embodiments, and as shown in Figure 6, rib 44 can wrap Include bar or the material of the such as steel etc on the surface 64 welding or being fixed to daughter board 60.But, can be some by removing Material realizes the saving of material to form cave 66 at the middle body of rib 44.This can be by from the contact of rib 44 The edge 68 of daughter board 60 removes material and realizes, so as to be formed in the length of rib 44 the continuous welding extended, Thus prevent from putting the stress riser of generation along weld seam at terminal or rise/off-position.The aspect of the present invention is not limited to this, other Structure is also feasible, and this includes entirely without ribs.

The connection between daughter board 60 and flange in forming board 26 may be configured to facilitation power smooth transfer.Such as Fig. 2 As visible with Fig. 4, by the mode of embodiment, the edge of plate main body 40 can mount to flange 24,28, The middle body of 48 and 58, rather than the marginal portion of flange.In this connection, apply to convex from plate main body 40 Edge or from flange apply to the active force of plate main body 40 substantially homogeneously crossed ledge surface apply and non-principal convex One edge of edge or side apply.

In the accompanying drawings, the flange 24 at the upper end 22 of forming board 26 and the flange 28 at lower end 30 with for and phase The lateral lip 48 of adjacent forming board coupling is shown with screwed joint.It is to be appreciated, however, that other class can be used The joint of type substitutes arbitrary or all flanges 24,28,48.By the mode of embodiment, the enforcement shown in Fig. 7 Mode, not used for being connected to the lateral lip of adjacent forming board, make use of welding in this joint on the contrary.

And, Fig. 7 Yu Fig. 8 shows the alternative that can be used for flange 70 at the lower end 30 of forming board 26 Embodiment.As indicated, be directed at the lateral edge of plate main body 40 and extend in the plane of forming board self Protuberance 72 may be integrally formed in arcuate flanges 70.Arcuate flanges 70 includes this protuberance or extension 72 can promote improved force stream and/or make to be soldered to plate main body 40 process be easier to.Such as institute in Fig. 7 Yu Fig. 8 Show, may utilize and include that casting is processed, thermoforming is processed, upwards welding processing and shaped by fluid pressure (naming just a few) are many The technology of kind forms arcuate flanges 70.

Fig. 9 Yu Figure 10 illustrates in greater detail an enforcement of footing 32 as applied in the embodiment of Fig. 2 Mode.Footing 32 has lower end 76, its be configured to be matched to offshore pedestal (other on the bank with or the class of offshore Like structure) the upper end of lower limb 8 (Fig. 1).Lower end 76 can limit the base of circular, and this base includes being easy to weldering Be connected to column tapered edge, allow grouting connect grout sleeve or can be used for column formed structure be connected other Feature.The upper end 78 of footing 32 includes being suitable to mating with the flange 28 (Fig. 2) at the lower end 30 of forming board 26 Arcuate flanges 80.The main body 82 of footing 32 have between circular lower end 76 and arch upper end 78 seamlessly transit with Stable force stream is provided, makes any stress riser amplitude that there will be minimize.

As shown in Fig. 9 Yu Figure 10, the upper arcuate flanges 80 of footing 32 can be orientated to have faying face 84, this knot Conjunction face is generally normal to the longitudinal axis 86 of the column for installing footing 32.Thus, execute from transition structure 20 Adding to most of active force (mainly compression stress) of column, can to cross the faying face 84 of arcuate flanges 80 the most direct Received in a compressed format rather than to shear or other form.Additionally, the end limited by the lower end 76 of footing 32 Seat general planar, and the longitudinal axis of lower limb or the column being correlated with can be substantially perpendicular to equally.

The arcuate flanges 80 of footing 32 and mating flange 28 and can have multiple structure at the lower end 30 of forming board 26. As indicated, flange 28,80 each extends about 90 degree of arcs, so, at least for utilizing the base with four columns For the embodiment of seat, these flanges together form a wholecircle.According to other embodiment, available long Or shorter curvature arc.The aspect of the present invention is not limited to this, other structure be feasible also it is conceivable that, this includes Variable curvature arc and include the arc of some linear segmented.
